Hey folks,
I'm trying to use xyling to generate tree graphs. Unfortunately, yap is
barfing on the output. When I try to run yap on the output, I get this
error:
"Some postscript specials could not be rendered."
This is Yap 2.4.1803.
So, how can I get yap to use a different ghostscript interpreter to see if
that fixes the problem? When I go view->Options->Postscript the interpreter
field is stuck on c:\progra~1\tex\texmf\miktex\bin\mgs.exe and I'm unable to
modify the field. I've looked through the registry and the various ini
files and I can't find where this setting is coming from.
Alternatively, is there another package that will draw tree graphs and let
me label the branches as well as the nodes that doesn't make yap fall apart?
I can view the output if I turn it into ps then launch ghostscript but
that's really slow and extremely annoying.
In case any of the specific error messages help, when I look at the
transcript, this is what I see:

This is an old problem: yap just cannot handle all postscript graphics.
However, a postscript output will no doubt look ok in ghostview and print
right too.
